How Much Does It Cost to Get an MC and DOT Number?

Getting a DOT number and an MC number costs $300 each in federal filing fees — $300 for USDOT registration and $300 for each type of operating authority you apply for.¹ That $600 is the entry point, not the finish line. Once you factor in mandatory insurance, the BOC-3 filing, Unified Carrier Registration, and — depending on your setup — a $75,000 broker bond, a realistic first-year budget for a new interstate carrier runs well into five figures.

The $300 USDOT Registration Fee

Every commercial motor carrier operating in interstate commerce needs a USDOT number, which functions as the carrier’s identifier for safety tracking and compliance.² Under the Unified Registration System fee schedule, the application costs $300.³ Government agencies and certain federally funded passenger transit carriers can have the fee waived. Everyone else pays the full amount.

Third-party registration services offer to handle the paperwork for roughly $200 to $500 on top of the government fee. FMCSA’s online Unified Registration System is built for self-service, and most carriers can complete the application without paying anyone else.⁴

The $300 MC Number Fee — And When You Pay It More Than Once

Operating authority, commonly called your MC number, is what legally permits you to haul freight or passengers for hire across state lines. Each type of operating authority costs $300 as a one-time, non-refundable fee.¹

The number of $300 fees you pay depends on which authorities you need. Applying for both common and contract carrier authority to haul property counts as one type, so it takes one $300 fee. Passenger authority and household goods authority, on the other hand, are different types — that means two separate $300 fees, or $600.⁵ Motor carrier authority plus broker authority also requires two filings at $300 each.³

A name change on an existing authority costs $14. Reinstating revoked authority costs $80.¹

Insurance — The Cost That Dwarfs the Filing Fees

Your operating authority will not activate until your insurance provider files proof of coverage with FMCSA. The federally required minimums depend on what you carry:

Non-hazardous property (for-hire, 10,001+ lbs GVWR): $750,000 in public liability
Hazardous materials, hazardous waste, and certain oil shipments: $1,000,000
Bulk hazardous substances and explosives: $5,000,000
Passengers, 15 or fewer including driver: $1,500,000
Passengers, 16 or more including driver: $5,000,000

Those are minimums under federal law.⁶ The premiums that buy that coverage depend on driving history, cargo, operating radius, and fleet size. A single-truck owner-operator hauling non-hazardous freight commonly pays $4,000 to $12,000 per year in primary liability premiums. A brand-new authority with no operating history almost always lands at the top of that range, and total annual insurance including cargo and physical damage coverage often reaches $12,000 to $20,000 or more.

Broker or Freight Forwarder Bond

If your authority is for broker or freight forwarder work, in addition to or instead of motor carrier authority, FMCSA requires a $75,000 surety bond or trust fund before it will grant registration.⁷ You do not put up the full $75,000. You buy a surety bond (filed as Form BMC-84) and pay an annual premium of roughly 1% to 10% of the bond amount, so around $750 to $7,500 per year depending on your credit and financials. The bond stays in place as long as you hold the authority.

BOC-3 and Unified Carrier Registration

Every carrier with operating authority must file a BOC-3 form designating process agents in every state where the carrier operates. Authority cannot activate without it.⁸ Blanket filing services typically charge $25 to $50 for nationwide coverage.

Unified Carrier Registration is a mandatory annual fee for interstate motor carriers, brokers, freight forwarders, and leasing companies, and the amount scales with fleet size. For 2026 the approved brackets are:

0–2 vehicles: $46
3–5 vehicles: $138
6–20 vehicles: $276
21–100 vehicles: $963
101–1,000 vehicles: $4,592
1,001+ vehicles: $44,836

Brokers and leasing companies pay a flat $46 regardless of vehicle count.⁹ Registration and payment must be complete before January 1 of the registration year for your authority to stay valid.

Heavy Vehicle Use Tax

If your truck has a gross vehicle weight of 55,000 pounds or more, the IRS charges an annual Heavy Vehicle Use Tax filed on Form 2290. The tax runs from $100 for vehicles at the 55,000-pound level up to $550 for vehicles over 75,000 pounds.¹⁰ The tax period runs July 1 through June 30, and the return is due by the last day of the month following the vehicle’s first use on public roads during that period.¹¹ Most carriers whose trucks are in service in July file by the end of August. A stamped Schedule 1 proving payment is required to register the vehicle in most states, so this is not optional in practice.

How Long Before You Can Actually Operate

Paying is the fast part. FMCSA says online applications from new registrants take 20 to 25 business days to process, and mail-in applications for existing carriers can take 45 to 60 business days.¹² Your insurer also has to file proof of coverage on your behalf, and if that filing does not happen within the FMCSA’s window your application can be dismissed.¹³ Lining up insurance before you file avoids the most common delay.

Recurring Costs After Your Authority Is Active

The application fees are one-time. Several of the costs that follow are not.

IFTA and IRP

Carriers running interstate deal with two fee systems. The International Fuel Tax Agreement lets you file fuel taxes with your base state instead of separately with every jurisdiction you drive through. The license itself is free or nearly free in most states, but quarterly returns and jurisdiction-by-jurisdiction mileage and fuel tracking take work. Many owner-operators pay a third-party service about $300 per year to handle IFTA filings.

The International Registration Plan covers apportioned plates for interstate travel, and its fees scale with your miles per jurisdiction, weight, and other registration factors. A smaller commercial vehicle may pay $500 to $1,000 annually. A typical semi-truck often runs $1,200 to $2,500 depending on how many states it operates in.

Drug and Alcohol Testing

Federal rules require pre-employment, random, post-accident, and reasonable-suspicion drug and alcohol testing for every driver of a commercial motor vehicle.¹⁴ Owner-operators and small fleets usually join a consortium to meet the requirement. Consortium membership for an owner-operator typically runs $145 to $200 per year and often includes one pre-employment test. Additional drivers in a fleet generally cost around $99 each after the first.

Carriers must also run annual queries on every current driver through the FMCSA Drug and Alcohol Clearinghouse.¹⁵ Each query costs $1.25.¹⁶ Small change for one truck, meaningful for a bigger fleet.

MCS-150 Biennial Update

Every carrier must update its registration with FMCSA every two years by filing a new MCS-150. Filing costs nothing.¹⁷ Missing the deadline is expensive: FMCSA can impose civil penalties of up to $1,000 per day, capped at $10,000, and can deactivate your USDOT number entirely.¹⁸

One more thing you should know about but will not pay a fee for: within your first 12 months operating, FMCSA will conduct a safety audit reviewing your compliance with 16 specific safety regulations.¹⁹ There is no fee, but failing it can revoke your new entrant registration. The cost is in the recordkeeping — drug testing program, driver qualification files, maintenance records, and hours-of-service logs — that has to be in order from your first day of operation.
